Ablation study on ADNI Phase 1 test set.

Prediction performance of the LSTM classification model on the ablation study. Each sociodemographic data variable, as well as the genetic data APOE-ε4 was subsequently omitted, prior to the MRI branding. Evaluation was calculated on the independent test set with n = 63 participants of the ADNI Phase 1 dataset. Visual representation were extracted using the ChestX-Ray8 database [16].

本消融实验中长短期记忆网络（Long Short-Term Memory, LSTM）分类模型的预测性能。在进行磁共振成像（Magnetic Resonance Imaging, MRI）标记前，我们依次移除了每一项社会人口统计学数据变量及APOE-ε4基因数据。模型评估在阿尔茨海默病神经影像倡议（Alzheimer's Disease Neuroimaging Initiative, ADNI）第一阶段数据集的独立测试集上完成，该测试集共纳入63名参与者。视觉特征提取工作依托胸部X射线8（ChestX-Ray8）数据集[16]开展。
